This web page contains information related to the effort to - improve SMP support in FreeBSD. In general, this project uses - what it can from the BSD/OS 5.0 development kernel, and - re-implements what cannot be directly used due to divergence in - the code bases.

As with any free software project, a detailed schedule is not - possible. We expect to have significant performance and - stability issues that need to be worked through over the first - several months of the project, though every effort will be made - to keep -current running as well as possible.
